ASoC: Updates for v4.14
This is quite a large release by volume of patches and diff, a lot of
that is mechanical cleanup patches but it's great to also see a range of
vendors actively working on adding new features and fixing issues in
their drivers. Intel and Realtek have been especially active here.
- Continued work towards moving everything to the component model from
Morimoto-san.
- Use of devres for jack detection GPIOs, eliminating some potential
resource leaks.
- Jack detection support for Qualcomm MSM8916.
- Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake
systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson
WM8523.
